Packages from the EU have been going through customs in the UK, which was fairly efficient. I haven't heard whether Brexit will change how mail to the EU is inspected and sorted. Anyone know?
yet. i have sent via parcel farce to usa using there premium service which is big bucks, it does give you up to date tracking and is faster getting through customs, probably because they use there own customs clearance.
